You should set the crossover to as high of a frequency as you can without messing up the soundstage by having the subwoofer give cues to its location. This turned out to be 80 Hz for me.
That may be fine if you have an AVR for digital playback. Don't they use a DSP for bass management?
Sure they do. You can come up with a pretty good duplication of what an AVR does with the right 2-channel 2-way electronic crossover.
But it's different with a two channel system, which is what this thread is about, especially if it's used for analog playback.
I don't know why analog playback would make a difference, unless by analog you mean LP in which case you are dealing with lower basic sound quality due to the well-known audible limitations of the LP.
As questionable as LP playback is, I think it would still benefit from clean bass response, which is what you avoid when you feed low bass into your main speakers.
I use a REL in a mostly analog two channel system. REL recommends using as low as a crossover point as possible, which is what I do, just to provide bass extension to my speakers, and not to take over any bass it is already capable of.
The questionable thinking there being that just because speakers have some kind of response at low frequencies doesn't mean that it is clean response.
If I turn the crossover even a little bit high (am at about 33 Hz) then the midrange loses definition and detail.
Pushing a source with inherent LF noise such as the LP through a 6 1/2" woofer is like asking, no demanding audible IM distortion.
I suspect that you are confusing modulation of the midrange with LF noise and low notes with "Definition and detail".
I have an old Harmonia Mundi recording (analog LP) of the Bach Toccata and Fugue in D Minor that demonstrates this very well.
More likely you are seeking a familiar rendition of IM distortion from your previous system as opposed to clean sound. 33 Hz is way, way too low for CM5s.
